Greener Roads.

Conventional stabilization (Cement/Lime) is carbon-heavy. GT-200L uses in-situ soils, virtually eliminating quarrying operations. The ionic reaction creates a hydrophobic barrier that prevents water absorption.

  • Non-Leaching Ionic Bonding
  • Zero Ground Water Toxicity
  • SABS / ISO 14001 Compliant
  • 28-Day Impermeability Achieved
